While en route to an agriculture application job, the airplane's engine exhaust started shaking, then smoke started coming off the engine. The pilot landed on a farm road. During the landing his visibility was limited by the smoke, and the right wheel went off the road into soft mud. The airplane swerved to the right and nosed over. Examination of the engine disclosed that the number four cylinder base nuts had backed off, allowing the cylinder to separate from the engine case.
Probable Cause: A loss of engine power due to the number four cylinder base nuts becoming loose, allowing the cylinder to detach from the engine case. Contributing to the accident was the pilot's impaired visibility due to smoke during the forced landing.
